No Comments on Why Enterprise Observability Needs Correlation

by Harish Vundavalli, 2026 August 25

It’s Monday morning. A dashboard turns red, alerts fire, and a stakeholder asks the one question that matters: “are users impacted?” Modern enterprises generate more telemetry than ever – metrics, logs, traces, and alerts, yet during real incidents, teams still lose critical minutes jumping between tools, comparing timestamps, and asking five different teams what they’re each seeing.

The problem isn’t a lack of data. It’s a lack of correlation. A single user click can travel through a portal, API gateway, identity provider, integration
layer, microservices, and a database. Each layer may be individually observable, but if the signals aren’t connected, engineers are left reconstructing the story by hand, under pressure.

Correlation-centric observability treats that connection as an architectural principle, not a post-incident scramble. Instead of five teams checking five dashboards, one connected transaction, carrying trace IDs, timestamps, and deployment markers across every layer show where a request slowed down, which dependency changed, and what’s at risk next. A weak signal in isolation (rising query latency, a growing connection pool) means little on its own; together, these signals reveal a failure path before customers ever notice.

This shifts the job of engineering teams. In a traditional model, they act like detectives, gradually building a theory from scattered clues. In a correlation-centric model, they act more like incident commanders, given connected evidence and blast-radius context so they can spend their time validating and mitigating rather than searching. The future of observability isn’t more dashboards, it’s better operational intelligence: one connected story, instead of disconnected noise.

Valuable Humans in Transit and Other Stories

Science Fiction for Engineers

Noting the high percentage of science fiction fans in the engineering community your steadfast Twin Cities ExComm has put forward the idea of a science fiction book club within our section and tasked me with nominating a quality title that appeals to geeks. This is my selection.

Cover courtesy of Amazon.com

Title:	Valuable Humans in Transit and Other Stories
Author:	qntm/Sam Hughes
Publication date:	October 31, 2022
Page count:	101 (MMP)

To the SF-loving engineer this anthology is a breath of fresh air. The author is a programmer and the absurdities of the software engineering profession inform his plotlines. Like Ted Chiang, he sports original ideas in a genre that has grown sadly repetititve over the last century. Likewise his output is so sparse that he has hung on to his day job, rather than publish drivel. I will focus on my 3 favorite (out of 10) stories.

3rd place: Lena

: “Lena” is a dry future history of the first successful download of a human brain that could be simulated on conventional computer hardware, written in the style of an article in the IEEE Transactions (or Wikipedia), carefully equipped with unelucidated acronyms, statistical data, and industry jargon. Although the subject is referred to as “he”, the focus is on how to manipulate the simulation into performing advanced AI tasks, while keeping a careful emotional distance from the concept of human rights. It is a mirthful jab at the tech industry and only true geeks will intuit where the title came from.

: You can sample “Lena” on the author’s web site.

2nd place: The Difference

: Nerds of a certain age will recognize the format of the bulletin boards that surged to the fore in the Internet of the early 90s replete with typing errors and references to popular video games. The forum is inhabited by a lost soul who claims to be locked in a prison with no memory of how he got there and no outside contact beyond the bulletin board. Passers-by briefly log in, interact with him, and log back out, in the style of a Kafkaesque nightmare, impelling the reader ultimately to a surprise ending.

1st place: The Frame-by-Frame

: The reader witnesses a ‘conversation’ among electronic control units of a motor vehicle moving at high speed along a highway, trying to identify and react to images picked up by its cameras. The CAN bus traffic has been translated to vernacular English but the messages between the ECUs are quite realistic.

: Published in 2022, “The Frame-by-Frame” was meant to be a warning about the risks of self-driving vehicles; but the scenario it describes actually happened in 2018.

Weighing in at only 101 pages, Valuable Humans in Transit‘s most serious liability is that it appears to be out of print. The Hennepin County library system has only 2 copies, but you can buy it (new or used) from Amazon.

N.B.: I have taken pains to avoid spoilers in this review. The same cannot be said for many on-line critics and I recommend you avoid them if you decide to read the book.

Twin Cities Section Webinar Series present “The Intersection of AI and Knowledge Acquisition”.

This virtual presentation will explore the dynamic intersection of Artificial Intelligence (AI) and education, dissecting its transformative effects on traditional paradigms. The discussions will span the optimal integration of AI into educational frameworks, encompassing considerations for curriculum development, teacher training, and institutional adaptation. Assessing students’ competence in a world enhanced by AI will be a focal point, addressing evolving methodologies aligned with the changing educational landscape. Furthermore, the presentations will delve into the dual role of AI in providing educational content and revolutionizing delivery methods, offering insights into the profound impact on the learning experience. Ethical and legal dimensions will be thoroughly examined, scrutinizing concerns such as data privacy, bias, accountability, and the responsible incorporation of AI technologies into educational settings.

The speaker will be Dr. Carlo Sapijaszko. Currently serving as the Senior Dean at Strayer University, Dr. Sapijaszko provides clear and effective leadership to the College of Technology and Professional Studies. Dr. Sapijaszko’s responsibilities include conducting holistic evaluations of IT and Professional Study programs, ensuring curriculum alignment with standards, and maintaining partnerships at national, state, and local levels. He worked in industry as a hardware and software Engineer at DE Labs and General Electric. He is a Professional Engineer with the Association of Professional Engineers and Geoscientists of Alberta, Canada.
